One Telegram Drop. bubop_cloud Leaked 27,942 Login Records.

In July 2025, a Telegram user released a stealer log package labeled bubop_cloud 449count containing 27,942 stolen credential records harvested from infected devices. The breach exposed email addresses, plaintext passwords, and URLs collected directly from victim machines during active browsing and login sessions. HEROIC dark web analysts catalogued this dataset as part of monitoring Telegram-based data sharing channels. With nearly 28,000 victims, this is a significant leak affecting individuals across multiple platforms and services -- and the 449-count label indicates this package was deliberately structured and organized before being shared, suggesting a sophisticated distribution operation.

Why This Is Dangerous

Stealer log data is often used within hours of being shared, as criminal networks quickly run credential stuffing attacks against popular platforms. Victims typically beleive their accounts are secure until unauthorized access has already occured. The scale of this dataset means automated attack tools can process all 27,942 records in minutes, testing each stolen email-password pair against banking apps, email providers, and e-commerce platforms simultaneously. Plaintext passwords remove the usual barrier of cracking hashed credentials, making every record in this collection imediately deployable.

What Was Exposed

• Email Addresses -- Email is the master key to your digital identity, used to recover and reset almost every other online account you own. Attackers use stolen emails to launch targeted phishing campaigns after gaining initial access.
• Plaintext Passwords -- Stored in cleartext, these passwords are instantly deployable by any criminal who downloads this dataset without any cracking required. Password reuse across services multiplies the damage.
• URLs -- Endpoint and API host URLs reveal the specific services victims were logged into at the time of infection, enabling targeted follow-on attacks against the accounts that matter most to each victim.

Why This Matters

With 27,942 credential pairs now in criminal hands, automated stuffing campaigns can simultaneously target banking apps, email providers, and e-commerce platforms. Each successful login gives attackers access to payment methods, personal communications, and the ability to lock victims out of their own accounts. Password reuse is the key enabler here: if the same password is used on even one other site, that account is also at risk. The timeline from leak to account takeover is now measured in hours, not days -- meaning every minute without action increases the risk of a successful breach.

How Stealer Log Works

Stealer log malware silently runs in the background of an infected device, capturing keystrokes, saved browser passwords, and active session cookies. The infection typically enters through phishing campaigns or trojanized software downloads, with victims having no indication their credentials are being harvested. Once collected, the data is compiled into structured log files and distributed through Telegram channels -- as occured in this case with the bubop_cloud 449count package. The 449-count designation refers to the number of credential batches organized within the package, reflecting the structured and systematic nature of how this stealer operation processed its stolen data.
